If everyone started spamming support as hard as possible in order to be “noticed”, the whole system would bog down and nobody would end up getting any help at all because the support techs would be too busy sorting through thousands of duplicate tickets.
Some combination of talking to cute girls on IRC and doing homework for one of my classes. More broadly, I just go do something else for a while.
One pattern I’ve noticed about Dreamhost support which I’ve experienced personally and seen to a degree here on the forum is that when it comes to technical issues, they tend to wait until they’ve fixed the problem before writing a response. I have no idea if that’s a policy of theirs or just the way things seem to work, but it is someting I’ve noticed. As a technically oriented person myself, I can appreciate this; that time spent saying “I’m looking into your problem” is time that I could be using to actually look into the problem instead.
If it’s been a few days and you still haven’t heard back, then it’s probably reasonable to submit another support ticket. Also, if you’re trying to debug the problem yourself and you happen to find some information that might be important, I’d probably send off another note that includes the new information. But otherwise, as they say, patience is a virtue.
